Usain Bolt and Shelly-Ann Fraser-Pryce both claimed their third golds of the competition as the respective 4x100 squads cruised to victories. Bolt's win was particularly significant as he drew level with Carl Lewis with eight World Championships golds.

Fraser-Pryce and teammates Carrie Russell, Kerron Stewart and Schillonie Calvert had fewer problems in their final as their nearest opponents USA gifted them victory with a clumsy second changeover.

Jamaica stopped the clock in a World Championships record of 41.29 seconds. France finished second but was disqualified, meaning USA took the silver in 42.75 seconds. Great Britain was promoted to bronze.

Kenya's Asbel Kiprop successfully defended his 1500 meters title with a comfortable victory in 3: 36.28.

Kiprop broke away with 60 meters to race and could not be caught. USA's Matt Centrowitz claimed silver in 3:36.78secs. South Africa's Johan Cronje took bronze on the line from Kenya's Nixon Chepseba.

Sum and Savinova had both caught and passed long-time leader Alysia Montano of the U.S. in the closing 50 meters. Montano missed out on bronze as Brenda Martinez pipped her on the line by 0.04 of a second.

Pichardo had been in contention with his jump of 17.68 meters until Tamgho clinched the title with his final jump.

USA's Will Claye, the Olympic silver medalist in London, took bronze with a leap of 17.52 meters.

Germany's Christina Obergfoll claimed javelin gold as her second throw went out to 69.05 meters.

Obergfoll ended up 2.45 meters clear of any of her rivals. Australia's Kim Mickle took silver with a personal best throw of 66.60 meters. Reigning champion Maria Abakumova of Russia settled for bronze.
